Museums Victoria was his next call; it eventually sent out a team to excavate the area, and several more 3-inch (9cm) teeth showed up right in the same spot, indicating the shark had died right there, 25 million years ago.
"These teeth are of global significance, as they represent one of just three associated groupings of Carcharocles angustidens teeth in the world, and the very first set ever to be discovered in Australia", stated Dr. Erich Fitzgerald, a Senior Curator of Vertebrate Palaeontology.
Paleontologist-a lover Philip Mullaly came across a unique artifact when walking through the countryside, Jan-JUC, located about 100 kilometers from Melbourne.
Mullaly told the press that he was out hunting for fossils in Australia when he noticed something promising.
A local museum confirmed that the 7cm-long teeth belonged to an extinct species known as the great jagged narrow-toothed shark. "I knew it was an important find, which you want to share with people".
Carcharocle angustidens inhabited the oceans of Australia about 25 million years ago, feeding on small whales and penguins. Their efforts yielded an impressive fossil find of 40 teeth, unearthed in late 2017. First of all, this is the first time that fossilized teeth belonging to this mega-shark species have turned up in Australia.

Later speaking in northeastern Rize province, Erdogan spoke of Turkey's plans to trade in local currencies with some countries. Deteriorating ties between the USA and Turkey - both North Atlantic Treaty Organisation members - have also alarmed investors.
"Angustidens was a bloody big shark, we're talking more than 30 feet long", said Dr. Erich Fitzgerald, Senior Curator of Vertebrate Palaeontology at the Museums Victoria in Melbourne, Australia.

Fitzgerald also determined that all of the teeth most likely came from the same individual shark. That cartilage does not easily decompose, which is why individual shark tooth fossils are somewhat common.
In the video below, Fitzgerald comments on the importance of this discovery and the contribution that citizen scientists like Mullaly bring to paleontology.
"The teeth of the sixgill shark work like a crosscut saw, and tore into the Carcharocles angustidens like loggers felling a tree".
"Sixgill sharks still exist off the Victorian coast today, where they live off the remains of whales and other animals".
